Need to unlock a couple of ES400s for World Wide demos. Currently these units will only accept AT&T SIM cards. Any help available? Thanks, TOm

http://support.symbol.com/support/search.do?cmd=displayKC&docType=k…; Multimode Enable V1.1 is a utility that will allow the user to unlock an ES400 or MC65 that has previously been locked to AT&T.    The currently released Rev  A  images have a feature that will lock the terminal to AT&T if an AT&T  sim  is inserted.    This utility will remove this restriction and allow the terminal to be used on both GSM/UMTS and CDMA/EVDO.

OK, that worked. Now where do I go to actually manage the SIM and enter a SIM enablement code? Thanks, Tom
